実験手順

N-[2-(3,4-Dichlorophenyl)-4-oxobutyl]-N-methylbenzamide (0.823 g) in methanol (4 mL) was added to a solution of 4-(2-oxo-1,3-oxazolidin-3-yl)piperidine (0.600 g) and acetic acid (0.20 mL) in methanol (8 mL). After 5 minutes, sodium cyanoborohydride (0.220 g) in methanol (4 mL) was added in a single portion. After being stirred for 3 hours, the reaction mixture was diluted with aqueous sodium bicarbonate, stirred for 30 minutes, and extracted with dichloromethane. The organic extracts were dried, evaporated, and chromatographed, with dichloromethane:methanol (gradient 98:2, 90:10) as eluent. The resulting material was dissolved in dichloromethane, precipitated as the hydrochloride salt with ethereal hydrogen chloride, evaporated, and placed under high vacuum overnight to give the title compound as a white solid (0.88 MS: m/z=504(M+l); Analysis for C26N31Cl2N3O3.1.20 HCl: Calculated: C, 56.96; H, 5.92; N, 7.66; Found: C, 57.02; H, 6.05; N, 7.62.
